Byron's analyst is a Phd (pile it higher and deeper) so I throw the low ball attempt at manipulation out.

I dusted off an old spreadsheet I did last year some time. I fgure that by 2014 one SGA plant will be running and orbite will be making 3-5 t/d of HPA so I expect a valuation of $30.50 to $44.50. (PE=10)

2013 is a different matter because there will be no SGA yet, say 3-5 t/d of HPA so ($21-$35). I would not expect these valuations untill after the feasibility study is complete. Now if the market actually wakes  up and realises what this technology can do the numbers could be stagering.
